Abstract

Acquired hemophilia is a bleeding disorder caused by the development of autoantibodies against plasma coagulation factors, most frequently against the factor VIII, or type A. We report a case of a 69-year-old patient with rheumatoid arthritis for 6 years with ecchymoses, hematomas and macroscopic hematuria, diagnosed with acquired hemophilia A secondary to rheumatoid arthritis, treated with methylprednisolone, desmopressin, activated prothrombin complex concentrate and cyclophosphamide, with remission.
